Method Detail

getType

ArrayTable.RepresentationType getType()

Returns the representation type.

freeze

java.lang.Object freeze(ColumnLoader.ValueSet valueSet,
                        int[] sources)

Converts a value set into a compact representation. If sources is not null, permutes.

getObject

java.lang.Object getObject(java.lang.Object dataSet,
                           int ordinal)

getInt

int getInt(java.lang.Object dataSet,
           int ordinal)

permute

java.lang.Object permute(java.lang.Object dataSet,
                         int[] sources)

Creates a data set that is the same as a given data set but re-ordered.

size

int size(java.lang.Object dataSet)

Returns the number of elements in a data set. (Some representations return the capacity, which may be slightly larger than the actual size.)

toString

java.lang.String toString(java.lang.Object dataSet)

Converts a data set to a string.
